Databinding is one of the most important aspect in ASP.Net. Databinding, and one does not think about using Eval and Bind methods, not possible. Mostly you will find these methods used in .aspx page, and within <%# and %> delimiters.

Both retrieve values from the data-bound fields underneath the data-bound controls and renders them to the html page within your data-bound controls. In addition to just retrieving the value from database field, the Bind method can also submit your changes back into the database. This is the main difference between Eval & Bind methods.

Eval is also called as read-only (select - database operation) method, and Bind is called as Read/Write (select, update, insert, delete - database operations) databinder method.

Get more details at MSDN explained very nicely.
